“…Prompted by these observations and starting from (Z)-3-benzylidene phthalide, the series of new 1,2,4-trazoles (3a-e), and 1,3,4-oxadiazoles (5a-f) were commonly performed under usual mild and thermal methods, while a simple and efficient one-pot procedure was followed for generation of 1,2,4-triazines (6a-f) with microwave assistance. The use of microwave energy to activated organic reactions has taken a new dimention in the last few years, due to its supreme properties represented by an excellent approach for the safe, rapid, enviromentally safe, inexpensive and yield enhancement (Deka et al, 2001;Chérouvrier and Bazureau, 2001;Xiuying et al, 2003;Yan et al, 2007).…”
